Improvement in the mode of

IMPROVEMENT IN THE MODE Specification forming part of Letters Patent No.20,624, dated June To all whom t may concern:

Be it known that I, GEORGE E. CLAY, of Stillwater, in the county ofXVashington and State of Minnesota, have invented a new and usefulImprovement in Lever-Powers, by which a rotary motion is transmittedfrom an oscillating or vibratory motion ot a lever; and I do herebydeclare that t-he following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making part ofthis speeilication.

Figure lis aside elevation of the improved lever-power. fig. 2 is afrontelevation ot' the same.

Similar letters refer to correspondingparts.

The nature of this invention and improvement consists in so gearing thevibrating' or oscillating arms, to which the ratchet-pawls are attached,together by a series of cog' wheels to enable a continuous rotar fmotion to be transmitted to a shaft by the vibratory or oscillatingmovement of a lever, on which the propelling-power is rst exerted.

To enable others skilled in the art to make and use my invention, I willproceed to de scribe its construction and operation.

The main horizontal shaft A turns in suitable boXes iixed in twouprights B of the frame and is provided with ratchet-wheels C C', fixedpermanently at each end, anda balance or tly wheel D, from which thepower can be conveyed by a band to any point desired. Inside theseratchet-wheels are arranged cog-wheels E F, turning loosely on the mainhorizontal shattone of them E being of the pinion size, smaller than theother F, and both being secured to bars G II, which oscillatc with saidwheels and extend radially7 from their centers to points beyond thenotched peripheries of the ratchet-wheels. These arms E F havespring-pawls 'I J attached to their extremities by pins, upon which theymove in such a manner as to enable said pawls to engage with theratchets on the wheels O when moving in one direction of theiroscillation, and to thus turn them and the shaft A, and to slip over thesame when moved in the opposite direction. The smaller cog-wheel orpinion E meshes in gear with a corresponding pinion K immediately aboveit, turning.;` looselyT on a stud or shaft fixed in the upright c, whichpinion K meshes in gear f with a corresponding pinion L above secured OFAPPLYING LEVER-POWER.

on the end of a horizontal shaft turning in suitable boxes in theuprights, and having a cog-wheel M secured on its opposite end, whichmeshes in gear with the cog-wheel F, with which it corresponds in size.

The lever N, to which the actuating` power is applied, is suspended on astud or bolt situated on the same plane as the center of the horizontalshaft A, and its handle may eX- tend to any desired distance beyond thestud, bolt, or tulcru 1n to correspond with the power desired to beobtained. Its inner end is made in the form of a segment of a circlescribed from the fulcrum on which it moves, and the periphery of thissegmentotawheel O iscogged and made to meshin gear with the pinion E, towhich the oscillating arm or bar Gis secured. Instead of arranging thislever N in the position represented, it may be placed immediately belowthe center of the horizontal shat't A and provided with a weight at itslower end, so as to enable it to be oscillated after the manner of aclock-pendulum.

The operation is as follows: \Vhen the outer end of the lever N isdepressed, the pinion E is turned by the rising ot' the opposite coggedsegmental end O of the said lever, with which it is geared, and with itthe arm or bar l, which carries with it. the ratchet-wheel C, with whichit engages through the agency of the sprin g-pawls. The other cog-wheelF andarm or bar II, secured to the same, is at the saine timerevolvedloosely over the horizontal shaft A, and its pawls are made toslip over the ratchets of the wheel C until it reaches the terminationot' its oscillation, when the outer end ot the lever N is raised and thepinion E and arm or bar G oscillated in a reverse direction, causing thepawls to slip loosely over the notches of the ratchet-wheel C and thecorresponding reverse oscillating motion to be given to the cog-wheel Fand arm or bar H attached through the agency of the pinions K L andcog-wheel M, and the springpawls to operate on the ratchet-wheel C', andby giving motion to the same continue the motion previouslygiventothehorizontal shaft A by the pawls and ratchet at its opposite end,and in this manner a continuous rotary motion is kept up by thevibratory or oscillating' movement of the lever if and the alternatecorresponding movements of the spring ratchet arms or bars.

I am aware that oscillattimg` spring-pawl arms or bars andratchet-Wheels have heretofore been employed for giving a continuonsmotion to shafts, and I do not, therefore, lary claim to these parts;but

That I do claim as my invention, and (lesire to secure by LettersPatent, is

The combination of the oscillating arms or bars G II, secured to thepinion E, and oogwheel F, which turn loosely on the horizontal shaft A,and pinions K L, and cog-Wheel M for gearing the two arms together,substantially in the manner and for the purpose de scribed.
